Data Accountability Center

Welcome to the Data Accountability Center (DAC)

This website provides public access to data about children and youth with disabilities served under the Individuals with Disabilities Education Act (IDEA) - Part B and C; technical assistance (TA) materials to support the collection, analysis and reporting of IDEA data; and the forms and spreadsheets used for collection.

DAC was funded in October 2007 by the Office of Special Education Programs (OSEP), U.S. Department of Education to provide information and TA to improve the quality of all state-reported data required by the IDEA.

Westat and its subcontractor, Louisiana State University Health Sciences Center–Human Development Center, operate DAC as a 5-year cooperative agreement with OSEP.

All documents and data on this site are the most current available. States may resubmit data at any time for up to 5 years past the due date. Revised/updated documents and data are posted as available or at least on an annual basis. Due to the time needed for data processing and validation procedures, it takes up to 10 months from when states submit data to posting of the data for the first time on the site. Send any questions or comments about this site to the webmaster.
